Collagen is a protein that is a fundamental building block of the body’s connective tissues. Collagen is the most abundant protein in humans and can be found in various parts of the body, including the skin, tendons, ligaments, bones, cartilage, blood vessels, and even the gut.

There are several types of collagen, the most important types of collagen for helping with the signs of aging are type 1 and type 3. Type I Collagen is the most abundant in the body and is found in skin, bones, tendons, and other connective tissues. It provides tensile strength and helps maintain the structure of these tissues. Type III Collagen is often found alongside Type I collagen, providing structural support to organs like blood vessels, muscles, the gut, and skin.

Collagen is synthesized by cells called fibroblasts, chondrocytes, and osteoblasts, depending on the tissue type. It is made up of amino acids and forms a triple helix structure that gives it its unique strength and stability. Over time, the body’s natural collagen production can decline due to factors like aging, sun exposure, and certain medical conditions. This reduction in collagen can lead to skin sagging, wrinkles, joint stiffness, and other signs of aging. As a result, collagen has become a popular ingredient in skincare products and supplements, and various medical procedures aimed at stimulating collagen production to improve skin texture and elasticity.
